The default setting is Do not turn off the UPS.
You can select Turn off the UPS if you want to preserve battery power. Some UPS’s do not support UPS turnoff through PowerChute or the NMC. For these models, it can only be done at the UPS itself. Please check your UPS documentation to ensure your model supports UPS turnoff.
If your UPS has Switched Outlet Groups, then the Turn off the UPS Outlet Group option enables you to turn off the outlet group that supplies power to the PowerChute protected server after a critical event occurs.

The default behavior for most UPS’s if they are turned off following an on-battery shutdown is that they will turn on again once input power is restored. The On-Battery Shutdown Behavior setting can be found in the NMC under Configuration – Shutdown where you can change the behavior to Turn off and Stay off if required. |

This is not available for an Advanced UPS Configuration that contains UPS Setups with Redundant UPS devices. |
In a Redundant UPS configuration you have the option to turn off one of the UPS’s after it has switched to battery power. This is designed to prolong the battery life and preserve the battery power of the UPS. If using this feature on a UPS that supports outlet groups the option "Turn off the UPS" should be enabled.
The load is still protected by the other UPS in the configuration.
After the specified delay, PowerChute will issue a command to gracefully turn off the UPS.

|
If one UPS is on battery and another UPS switches to battery before the configured delay for Single UPS turn off has elapsed, then the first UPS will not be turned off. |
 |
If the shutdown action is enabled for the On Battery event, a Multiple Critical event condition will occur if a second UPS switches to battery power (after the first UPS has been commanded to turn off by PowerChute). When this occurs the shutdown sequence will start after 10 seconds. |
